Description

Mobile millimeter wave human body security inspection system
Technical Field
The invention belongs to the technical field of human body security check equipment, and particularly relates to a mobile millimeter wave human body security check system.
Background
At present, the commonly used security detection means are a metal detection door and an X-ray machine, metal detection people cannot effectively detect contraband except metal, typical dangerous goods cannot be detected (ceramic tools, powder explosives, liquid explosives, gasoline, diesel and kerosene), detected dangerous goods are not detected (mobile phones, coin, keys and metal cosmetics), and X-ray has too large photon energy, can cause ionizing damage to human cells, and is extremely harmful to human bodies. Currently, European and American countries are forbidden.
The millimeter wave has human safety because the photon energy of the millimeter wave is very small, does not cause ionizing damage to human cells, and is safe to human bodies. Millimeter waves refer to a section of electromagnetic waves with a frequency between 1mm and 10mm, which is technically considered to be 26.50GHz-300 GHz. The millimeter wave has penetrability to nonmetal and nonpolar substances, and is very suitable for detecting human bodies and various dangerous goods hidden in the skin and clothes of the human bodies.

Millimeter wave security inspection systems in the prior art are mainly classified into two categories, one is a passive security inspection system, and the other is an active security inspection system. The passive security inspection is characterized in that: one is non-contact, does not need to search for the body, respect to the personal privacy of the person to be detected; secondly, the detection efficiency is high, the speed is high, no stay exists, the detected personnel can finish the security check after normally walking and passing through the specified security check channel, and the security check efficiency is greatly improved; and thirdly, the device is safe and free of radiation, is similar to common cameras and monitoring cameras, does not generate electromagnetic radiation and ionizing radiation, and is harmless to human bodies. The disadvantages are low resolution and low signal-to-noise ratio. The active security inspection system is used for imaging a human body by actively transmitting a certain dose of millimeter waves (within an acceptable range dose), and compared with a passive security inspection instrument, the signal-to-noise ratio is higher. Although a certain radiation dose exists, the millimeter wave photon energy is small, so that ionizing damage to human cells can not be caused.
The existing millimeter wave human body security inspection system is all fixedly placed, a person to be detected needs to receive detection in a specific area, and the detection distance of the existing security inspection system is limited and is about 0.5 to 3 meters. In order to extend the detection distance and to enable security detection of any desired region, a new form of millimeter wave security inspection system needs to be developed.
